Answer:
AECG
Step-by-step explanation:
1
sqrt(49) = 7
sqrt(a^2) = a
sqrt(b^2) = b
For every two variables you can take one out from under the root sign and thorough the other one away.
Answer: E
2
sqrt(36) = 6
sqrt(a^2) = a See comment for 1.
b must be left where it is. There is only 1 of them.
6asqrt(b)
Answer: A
3. sqrt(25) = 5
sqrt(b^2) = b
a must be left alone. There's only 1 of them.
5b sqrt(a)
answer: C
4
sqrt(81 a b)
sqrt(81) = 9
The variables must be left alone. There's only1 of them
9 sqrt(ab)
Answer G
Let's say that the shorter piece is x and the longer piece is 5x (because it's 5 times as long). x+5x=72 and 6x=72. Dividing both sides by 6, we get that x=12, and 72-12=the length of the other piece (since there are only 2 pieces)=60
Answer:
f(3)=2
Step-by-step explanation:
To find f(3), we simply need to find the ordered pair at x=3.
From the graph, we can see that the ordered pair at x=3 is (3,2).
Thus, f(3)=2.
And we're done!
Answer:
3.33 ounces in each bowl
Step-by-step explanation:
7.49 + 6.26 = 13.75
subtract 0.43 and that equals 13.32
13.32 ÷ 4 = 3.33
I hope this helped :/
Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is y2-y1/x2-x1
= 10/1/ 3-0
= 9/3
= 3.
Using the point-slope form for a straight line:
y-y1 = m(x-x1) (m = slope)
y - 10 = 3(x - 3)
y - 10 = 3x - 9
y = 3x - 9 + 10
y = 3x + 1 is the required equation.
